The criminal investigation into Kevin Spacey's alleged groping of a recent high school graduate in the summer of 2016 appears to be one step closer to resulting in formal charges against the actor.

On Monday, the mother of the alleged victim appeared on Megyn Kelly Today with an update on the investigation into her son's claims by the Nantucket County Sheriff's Department.

'There is evidence. Because there's an ongoing police investigation, I'm not able to talk about what that evidence is. But there is evidence,' revealed Heather Unruh.

'And there are witnesses.'

The NCSD would not comment on the investigation, citing Massachusetts privacy laws involving victims of sexual assault, but a spokesperson for the Cape and Islands District Attorney's Office was able to give an update on the case.

'We are in touch with the attorney who represents the individual who made the allegations,' Assistant District Attorney Tara L. Miltimore told DailyMail.com on Monday.

'A meeting has been scheduled. The matter will proceed from there.'

When asked about what she believed would happen next in the case during her appearance on Today, Unruh said: 'I think he has run out of using his celebrity. So I think we are not going to stop until he pleads guilty.'

Unruh later said that since getting her son's blessing to come forward and share his story she has been contacted by eight individuals who also claim they were victims of Spacey's sexual moisconduct - including at least one on Nantucket.

She began the interview by sharing more details about what allegedly happened between the Oscar-winning actor and her son, who had just graduated high school and was working on Nantucket for the summer.

'He was not expecting it. This was over the course of - I can't say how many minutes. They were together for a while,' said Unruh of the alleged assault.

'It happened when my son got off of his shift. A late-night shift bussing tables in the Club Car restaurant, and the Club Car bar is attached to it.'

Unruh continued: 'Just as my son got off work, he was introduced to Kevin Spacey. He was thrilled, thinking this has to be the greatest night of my life. And they talked for a long time. They sang together at the piano.

Unruh remained steely throughout the interview, showing no tears but plenty of determination as she spoke of her desire to see Spacey be punished for this alleged offense, claiming that her son is just one of many victims.

'It’s an abuse of power and fame. He lures them in, making them feel like they are the greatest person, that he is really interested in what they have to say and they have a great conversation,' explained Unruh of how she believes Spacey operates in these situations.

'And he strikes when they least expect it, just when they start to feel comfortable with it. To be honest with you, I’ve heard from at least eight other alleged Spacey victims, and I think there are so many more still afraid to come forward. Or just too embarrassed.'

And while she admitted that she and her family are both being ridiculed and in some cases attacked on social media, the good far outweighs the bad now that her son has been able to speak out.

'I would think it was worth it, even if we had been bullied more than we have been,' said Unruh.

'But it’s been hard to take, my son doesn’t see it much because he is in that university bubble, he is in college. I see it every day.'

She then added: 'But would it deter me from coming forward again with it? Absolutely not because until we call these people out for the victim shaming and blaming that they do, we are never going to see change for everyone else.'

Unruh previously said during an appearance on Today that Spacey repeatedly stuck his hand down the pants of her 18-year-old son but he was eventually able to get away when a woman walked over to him while the actor was in the bathroom and said: 'Run!'

At the time, Spacey was trying to convince the boy to join him at a party said Unruh, who now hopes to find the mystery woman who she believes saved her son from a far worse fate.

When the boy eventually got to his grandmother's home, he told his younger sister what had happened and then called his mother.

Unruh had tears in her eyes as she recalled the conversation, which began with her son stating: 'Mom, Kevin Spacey tried to rape me.'

DailyMail.com uncovered multiple photos of Spacey from that week in Nantucket back in 2016, including one taken with a co-worker of the victim at the Club Car, where the alleged assault took place.

Another shows the Oscar winner, 58, with his constant companion, manager and former pop star Evan Lowenstein while one posted by the actor himself shows him flying in a private plane to an event in nearby Boston.
